Peritonitis Caused by Haemophilus parainfluenzae,Leifsonia aquatica,and Gordonia spp. in a Patient Undergoing Continuous Ambulatory Peritoneal Dialysis

Abstract

Abstract

Background:

Peritonitis has remained the most common serious complication of continuous ambulatory peritoneal dialysis (CAPD). In most cases, these infections are monomicrobial, and the pathogens involved most commonly are Staphylococci. Recently, polymicrobial infections with rare organisms have been reported more often.

Case Report:

We describe a patient who developed recurrent episodes of CAPD-associated peritonitis with a total of four pathogens: Methicillin-resistant S. aureus, Haemophilus parainfluenzae, Leifsonia aquatica, and Gordonia spp. The infection most likely was acquired when the patient used tap water for dialysis during a camping trip. All episodes were treated successfully with antibiotics. Finally, the device was removed, and later, a new catheter was implanted, which still is in use.

Conclusion:

Peritoneal dialysis-associated peritonitis may be caused by rare organisms. Antibiotics may be able to treat disease temporarily, but removal of contaminated catheters usually is required.
